Sanic Ring!

Okay, I was thinking of an awesome idea.
Because sanic drops a sanic head, I thought to myself : hmmm, Sanic collects rings, you wear rings in rotmg, sanic is in nillys, So, Ladies and Gentlemen I present to you, THE SANIC RING!

Sanic Ring
Description: Wearing this ring, you feel a strange urge to travel faster than light.

Stats: +20 speed +5 dex, -8 def and -3 vit, -50 hp

Drops From Sanic at a 1/3000 (0.0003) Chance.

Why is this item is unique and balanced:
Well, you might be thinking +20 speed and +5 dex is a bit overpowered, but if you are using this ring for rushing, the -8 def will be a problem since you will be taking more damage and the -3vit will cause you to regen slower, with the addition of -50 hp, this would be great for a knight since he already has lots of hp, def and vit.

(This is my first idea by the way :D)
Please leave some constructive criticism on how I can make this better, thanks :D!
EDIT: Added a small bit of shading to the ring to make it look like the light it shining onto it :D
EDIT: Changed -5 Vit To -3 Vit and added -50 Hp

In my opinion, you should scratch "serious" descriptions when suggesting things for memey stuff. It should be like: "It's no use!" or "You're too sloooooow!". It may sound cringy, but hey, it's Sonic.
My opinion. No force, it's your choice.

Never take internet insults seriously. In no way it should affect your life, because you can say ANYTHING on the internet. So man up and grow some balls.

@maksimUT Warrior and Pala is okay with the ring, due to the ability of having Invincibility.

Knight is given no shit throughout the game. Know why?
He'll mostly be killed, and in bosses like O3-O4, even with this ring, he'll be traced by the O3-O4 bullets, and maybe even hit the confusion bullets. He had no Invincibility buff, thus him being the weakest of the three melees.
This ring gives him a chance for redemption, not make him OP.

@BreadStick I think, since the sonic head is very rare, as with the sonic ring, getting both of them might be near to impossible so only one item is required to give the skin, and with the stats, out of interest what would you make it?
